VAPORIZER.

To all whom it may concern 7 Be it known that we, JOSEPH A. NICKEL- SON and JOHN FREnRIKsoN, citizens of the United States, and residents of the borough of Bronx, city and v invented certain new and useful Improvements in Vaporizers, of which the following is a specification accompanied by drawings; This invention relates to Vaporizers for vaporizing heavy liquid hydrocarbon fuels, such as kerosene, for combustion engines, and the objects of the invention are to enable a cheap and simple apparatus to be connected with the exhaust pipe of the engine, without complicated parts to get out of order. Another object is to produce a vaporizer which Will permit a free flow of the gases and will not burn out under high temperatures.

To these ends the, preferred form of the invention is shown in the accompanying drawings, in which- Figure 1 is a side elevation of a combustion engine having a' vaporizer embodying the invention;

Fig. 2 is an end view of the apparatus with part of the engine to the center line removed;

Fig. 3 is an enlarged longitudinal sectional elevation through the vaporizing chamber on line 3-3 of Fig. 4 with part, of the exhaust,pipe broken away; and

Fig. 4 is a horizontal sectional view of Fig. 3 on line l4.

Referring to the drawings, A represents :a combustion engine, having. the usual carbureter B of any suitable type, connected by pipe C to the vaporizing chamber D, preferably located in the exhaust pipe E of the engine. The vaporizing chamber D also communicates with the engine cylinders by means of the intake pipes or manifold F.

he vaporizing chamber is formed by means of headers G and H suitably provided in the sides of the exhaust pipe E, in this instance the headers being formed in one piece with the exhaust pipe, although other methods of construction may be employed.

Vaporizing tubes J are set into the headers G and H in any suitable manner, andthese tubes should preferably be made of brass or other suitable metal,which will withstand high heat forconsiderable periods of time without deterioration. We have Specification of Letters Patent.

State of New York, have x the tubes.

found brass to be the best material so far known to us for the vaporizing tubes.

iOver the header G is placed a cap K, preferably bell-shaped, and connected to the pipe C While a similar shaped cap L is placed ofer the header H and connected to the en gine manifold F. It will be observed by reference to Figs. 3 and 4. that the caps K and L form. enlarged chambers over the ends of the vaporizing tubes, so that the entrance andexit of the gases to and from the vaporizing tubes is substantially free and unobstructed. This is a feature of material importance.

Furthermore, the fact that the gases pass through and notv over the vaporizing tubes is of great practical importance, because in this way more perfect vaporization is secured, owing to the free mixing passages for the gases. The gases will pass more freely through the tubes than over them, and the design of the apparatus is to and unobstructed passage directly through Both the exhaust pipe/l2) and vaporizing chamber are preferably water jacketed by means of the jacket P, in order to enable the temperature of the vaporizing chamber to be controlled within desirable limits, as otherwise its temperature has been found .to increase to a degree beyond that required for proper vaporizing.

We claim and desire to obtain by'Letters Patent the following:

1. A vaporizer for heavy liquid hydrocarbon fuels, comprising in combination witha combustion engine and its horizontal exhaust pipe, of upper and lower cylindrical headers in the top and bottom of said exhaust pipe, forming "a cylindrical vaporizing chamber, vaporizing tubes inserted vertically 1n sa1d headers and lying within the vaporizing chamber, upper and lower bellshaped caps over each of said headers, a fuel condult communicating centrally with the lower one of said bell-shaped caps and leadlng to the carburetor of the engine, and the intake pipe or pipes of the engine communicating centrally with the upper one of sa1d bell-shaped caps, whereby the fuel to be vaporized passes freely through the heated vaporizing tubes, and the hot exhaust gases pass around the tubes, and a water jacket surrounding both theexhaust pipe and the sldes of the said '75 provide a free I cylindrical. vaporizer chamber, to prevent bon fuels, comprising in combination with a combustion engine and its exhaust pipe, of a vaporizing; chamber formed in said exhaust pipe and having walls extending at substantially right angles outwardly from the walls of said pipe, headers covering the outer ends of said vaporizing chamber, vaporizing tubes inserted in said headers and lying within the vaporizing chamber, or ps over each of said headers, a fuel conduit communicating with. one of said caps and leading to the carburotor of the engine, and the other cap communicating; with the engine manifold, whereby the fuel to be vaporized pas through the heated. vaporizing tubes and the hot exhaust gases pass around the tubes, and an outer wall forming a water acket around the errhaust pipe, said wall also being" extended outwardly at an angle adjacent the Walls of the vaporizing chamber to form a Water jacket partially surroundingthe said Vaporizing chamber, to cool the exhaust gases and prevent the temperature of the vaporizing chamber from increasing beyond a predetel-mined limit.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
